The WINDEX was first designed and brought to market in 1964 by RADAB (Research And Development AB), a small company run by three young engineers who also happened to be close friends, Sven-Olof Ridder, Harald Undén and Lars Bergström.
This design, which incorporates the now famous Sapphire jewel suspension has remained unchanged and extremely popular with sailors through the decades.
Today the Windex Sailboat Wind Indicator is used on most family cruisers as well as the top Ocean Racers all over the world.
